Has this been asked before?? If I am still bringing the bike to the shop for service do I need to remove this before hand? Will it screw up any computerized testing they do?

If it is of concern, you can move the jumper to the -0º setting. This essentially returns the bike to stock condition. Or you can simply unplug it.

But as has been noted it really shouldn't make any difference.
